We demonstrated the first operation of an on-chip integrated optical-to-terahertz signal converter using ring-shaped microstrip line with GaInAs photoconductive mesa structure. The proposed device directly converted the long-wavelength communication band optical signal to 300GHz teraherts signal. As a results, the device successfully performed 16.5dB extinction ratio at input optical power of 32 mW.
